Strawberries and oranges are high in Vitamin C (in fact, a cup of strawberries has more Vitamin C than a medium-sized orange) as well as potassium. We can thus infer that Layla is probably deficient in these nutrients. To supplement Layla's intake of Vitamin C, Ruby can serve red and green peppers and kiwi, which (like strawberries) have more Vitamin C than an orange. To supplement Layla's potassium intake, Ruby can serve spinach, broccoli, and cantaloupe.
